Evidence synthesis for Fern

Reducing gold-mining harm without shrinking people's options

A livelihood-centred just transition for Ghana—designed to prevent exclusion, capture and displaced harm.

Ghana as the main caseWest African and international responsibilitiesEvidence cutoff: 2 October 2026

The decision

The question is not simply how to stop galamsey

What combination of support, rules, purchasing, accountability and cooperation can reduce total harm while expanding people's real options?

Reduce absolute harm

Land, water, toxic exposure, unsafe work and unrestored sites—not arrests or licences as proxies.

Expand real options

Income, timing, land, credit, buyers, safety and power sufficient to refuse harmful work.

Prevent cost-shifting

No relocation of extraction, pollution or exclusion to other people, places or trade routes.

working proposition

Evidence discipline

Four claim types—kept visibly separate

evaluated effect

A counterfactual design estimates what the intervention changed.

observed mechanism

Descriptive, qualitative, spatial or implementation evidence shows how a process operated.

official design/status

An institution documents what it launched, planned or procured—not what it achieved.

working proposition

An inference fits several sources but has not itself been evaluated.

Audit rule: legal status, licences, arrests, equipment distributed, official purchases and export volume are implementation or market indicators—not livelihood or environmental outcomes.

The Ghana livelihood spine

Three questions keep change and inequality in view

Q1

What livelihood portfolios existed before and after ASGM, and what influenced change?

Q2

What were the livelihood impacts of ASGM's emergence?

Q3

What opportunities and barriers shaped different livelihood trajectories?

observed mechanism

Method: 360 households, 30 oral histories, three focus groups, five key informants and transect walks in three selected Atiwa West communities. A 2021 cross-section retrospectively reconstructs 1992–2021; it is not a longitudinal panel or national estimate.

Q1 · Before and after

Mining entered a portfolio; it rarely replaced one job with another

Before ASGM's rise

Cocoa and food crops, livestock, fishing, forest products, trade, craft work and migration. Roads, electricity, telecommunications and cocoa support were already changing options.

After about 2010

Agriculture remained important while mining, agricultural trade, transport, food, rentals, repairs and construction expanded. Farming could be financed by mining, combined seasonally—or displaced by it.

76%

Average reported household-income share from ASGM among surveyed mining households.

13 · 17 · 34%

Mining participation differed across the three communities: context mattered even inside one district.

local descriptive evidence

Income is self-reported. Baddianaah et al.'s mining and other-income means use different denominators and do not establish comparative returns.

Incentives and constraints

Why mining can be attractive—or difficult to refuse

Cash now

Frequent and potentially high payments can meet food, health, school and debt needs before seasonal agriculture pays.

Farm pressure

Input costs, rainfall and price risk, weak credit, labour loss and land degradation make agricultural income uncertain.

Low entry—unequal advancement

Casual work may be accessible, while ownership, machinery, licences and profit require land, finance and networks.

Buyers and credit

Nearby traders and advance finance make gold liquid. Removing them without replacing their functions can deepen dependency.

Land relations

Owners can lease or mine; tenants can lose farms and be pushed towards wage mining or distant land.

Local multiplier

Mining demand supports transport, food, repair, accommodation, trading and other services beyond the mine site.

The policy target is a system of functions—not a single occupation.

observed mechanism

Q2 · Impacts

Gains and damage can be real at the same time

Expanded options for some

  • cash, jobs and business demand
  • assets and finance for schooling or health
  • capital for farming and diversification
  • new networks, skills and local markets

Contracted options for others

  • farm, forest and water loss
  • pollution, unsafe pits and unreclaimed land
  • higher food costs and reduced farm labour
  • weak compensation and insecure tenure

A household can gain income while its community loses water, land or future options.

observed mechanism

The two Adranyi papers analyse the same field project and sample; they are not independent confirmation. Reported damage was not paired with laboratory testing in that project.

Q3 · Unequal trajectories

ASGM opened different paths because people started with different power

Consolidating

Land, businesses, machinery, finance, skills, influence and networks enabled mine operation, leasing, equipment rental and further accumulation.

Fluctuating

Mining and service income raised living standards or financed assets, but weak credit and mobile/closing sites made gains unstable.

Marginalised

Tenants, land-poor households, some women-headed households and migrants faced insecure land, restricted access, degradation, weak compensation and casual work.

Pre-existing assets shaped access to opportunity; mining could then deepen the divide.

analytical classification

The three groups are constructed from 12 livelihood indicators and then compared on related indicators. They illuminate pathways; they do not prove that ASGM caused each outcome or define fixed social classes.

Why impacts multiply

Six conditions turn a livelihood shift into a reinforcing system

Land and tenure

Owners can authorise or capture value; tenants and customary users can lose access without equivalent compensation.

Finance and equipment

Capital enables scale, speed and mobility. Debt and advance finance can bind gold to particular buyers.

Political protection

Influence can shape licences, enforcement and site access while weaker actors remain exposed.

Institutional fragmentation

Mining, water, land, agriculture, labour, health and purchasing can optimise different objectives.

Weak alternatives

Training without land, buyers, childcare, finance or bridging income creates enrolment—not an option.

No remedy

Unrestored sites, health costs and polluted water transfer losses to neighbours, public services and future users.

mechanism synthesis

Distribution

“Smallholder” and “miner” each conceal unequal positions

Measure outcomes by role, rights and exposure—not only by household or community average.

evaluation requirement

Gender

The problem is not only vulnerability; it is how reform travels through male-controlled assets

14% / 64%

Women / men reporting digging.

2% / 11%

Women / men heading teams.

8.7% / 17.2%

Women / men reporting training.

almost none

Women among reported licence holders.

Women were concentrated in carrying, grinding, washing and services. Mining could still pay more than their outside work—so abrupt exclusion and licence-centred support can both harm.

multi-country descriptive evidence

Buss et al.: 878-person purposive survey across gold and 3T sites in DRC, Rwanda and Uganda, plus 60 focus groups and 28 life histories. It diagnoses mechanisms; it does not evaluate a reform or establish Ghanaian prevalence.

Affected communities

People who receive little mining income can carry the largest cumulative cost

  • neighbouring and downstream residents
  • tenant farmers and farm workers
  • fishers, livestock and forest-resource users
  • children, caregivers and injured former workers
  • future users of land and water

Measure exposure, not only perception

Obiri et al. repeatedly sampled ten water sites over ten months and surveyed 250 residents. Laboratory QA was disclosed; many sampled-site metal levels exceeded drinking-water guidelines and residents reported water and farmland loss.

But no control watershed or mine-level tracing separated ASGM from other surface mining sources.

integrated descriptive evidence

Outcome discipline

Three outcomes must not be conflated

Less harmful mininglower exposure and damage per unit
Less miningsmaller absolute footprint where extraction must fall
Secure exitpeople can stop without losing basic security or power

Technology, licensing and purchasing may improve the first while increasing extraction. A ban may reduce visible activity locally while failing on livelihoods and displacement.

No retained independent evaluation measures Ghana's current package across harm, livelihoods, distribution, rights and displacement.

official status + evidence gap

Measure 1 · Restrictions

A restriction can protect a place—and still produce a harmful transition

When it may help

Credible enforcement of no-go zones or imminent-danger rules can stop activity in bounded places, especially when organised finance and equipment are targeted.

When used alone

Income disappears before demand or productive capacity; activity can hide, move, become more dangerous or be mediated through bribery and powerful operators.

Ghana's qualitative study documents hardship and coping among 58 selected former young miners—not the ban's national net effect.

Ghana mechanism evidence

The DRC and coca cases test displacement mechanisms under very different conflict, commodity and institutional conditions. They generate questions for Ghana; they do not predict Ghanaian effect sizes.

Measure 2 · Livelihood alternatives

An alternative must replace functions—not merely offer an activity

Incomeadequate net earnings
Timingcash when bills arrive
Inputsland, credit, assets, care
Marketreliable buyer and price
Riskweather, debt and failure protection

Without an explicit substitution pathway, farming, training or a small business may simply join the portfolio while mining continues.

review + mechanism evidence

Roe et al. screened 22,146 records but only 21 studies met effectiveness-review criteria; evidence was too sparse and heterogeneous to name a universally effective livelihood alternative.

Measure 3 · Formalisation

A licence can open a pathway—or concentrate control

Possible pathway

Visible operations, more secure tenure, investment, inspection, safer schedules, wages, insurance and professional environmental capacity.

Possible exclusion

Cost, delay, unsuitable land and paperwork privilege connected operators; workers remain informal beneath a licence; new credit and machinery can expand extraction.

Formal status is an input. Conduct and outcomes are the test.

Ghana process evidence + comparative spatial evidence

The Peru study uses Landsat, fixed effects, matching, 47 interviews and focus groups. Titling was not random; concurrent prices, roads, enforcement and politics remain alternative explanations.

Measure 4 · Cleaner technology

Efficiency can reduce exposure per unit—and increase total extraction

Adoption

Can miners afford and access the equipment?

Use

Is it used correctly and consistently?

Maintenance

Who pays for parts, repairs and oversight?

System effect

Does higher recovery expand mining or displace women?

The evidence contains abandoned equipment, maintenance failures, weak gender results and unmanaged toxin substitution alongside some sustained improvements.

systematic review + independent evaluation

Tsang et al. found ten eligible occupational-health interventions and no demonstrated human-health benefit in the technology studies. GEF evidence combines case visits, project records and stakeholder recall; it does not estimate one common causal effect.

Measure 5 · Purchasing and traceability

A formal transaction can sit on top of harmful extraction

What changes sales

Competitive price, prompt payment, proximity, trustworthy assay, working capital and continued market access.

What changes production

Verified mine origin, corrective finance, worker and community evidence, environmental limits, sanctions and public coverage data.

Traceability can make records inspectable. It does not itself create clean production, fair distribution or remedy.

implementation evidence

The DRC reports are implementer evidence with low initial coverage and substantial subsidy/support. GoldBod's 2026 pages document a pilot and procurement—not a completed national system or verified mine-level results.

Move responsibility up the chain

Buyers and financiers have leverage—but disengagement can export the problem

Corrective engagement

Long-term purchasing, compliance finance, transparent assay/pricing, verified improvement, community evidence and remediation.

Risk dumping

Buyer withdrawal, costs pushed onto miners, paperwork without mine verification, or gold redirected to less accountable routes.

≈ 11

additional homicides per 100,000 estimated in more-exposed Brazilian municipalities after a 2013 rule weakened first-buyer checks; mining-related deforestation also rose.

quasi-experimental comparative evidence

Brazilian exposure is geological/spatial rather than observed transactions; the mechanism is indirect and livelihood/displacement outcomes were not measured.

Learning elsewhere

Other sectors reveal conditions—not templates

Afghanistan · drug crops

Replacement fails when a crop also supplies credit, land access, labour demand, cash timing and risk management.

Uganda · forest payments

Two years of payments roughly halved short-run tree loss among treated villages; only 32% of eligible owners enrolled, clearing resumed after payment, and neighbours' access may have been restricted.

Cash-plus programmes

Income protection supports consumption; livelihood-oriented complements can improve average economic outcomes, but do not prove exit from harmful activity.

Labour-market programmes

Training effects often take years and assume jobs exist; rapid restrictions cannot rely on future skill gains.

Fisheries co-management

Rights, diverse user involvement and adaptation correlate with better outcomes, but evidence is mostly observational.

Coal transitions

Formal-worker packages can miss women, informal workers, care burdens, secondary employment and place-based loss.

cross-sector transfer hypotheses

The package logic

Four jobs must be performed together

Protectincome, food, health, debt and rights during disruption
Createviable pathways with land, finance, buyers, skills and care
Constrainecological limits and duties for organisers, buyers and financiers
Repairland, water, health and lost livelihoods with remedy

Creation without constraint can add another activity. Constraint without protection can destroy options.

research-supported architecture

No reviewed study evaluates this complete Ghana package. Cross-sector reviews support a configurational approach, not a universal recipe.

Policy architecture

Nine functions; instruments chosen locally

01

Ecological guardrails

Absolute limits, places and deadlines.

02

Transition floor

Income, food, health and debt protection.

03

Real capabilities

Land, finance, buyers, care and viable work.

04

Attainable legal route

Suitable land, proportionate rules and shared services.

05

Power and value

Rights, organisation, prices and co-decision.

06

System constraint

Duties for organisers, equipment, finance and buyers.

07

Repair and remedy

Restoration, health, compensation and appeals.

08

Spatial coordination

Detect relocation, diversion and laundering.

09

Durable governance

Multi-year finance, evaluation and correction.

common functions · local design

Sequence matters

Support must become real before most restrictions remove income

Beforemap roles and rights; set limits; establish income/debt protection; secure land, finance and buyers
Duringphase restrictions; enable compliance; protect workers; verify purchasing; fund restoration
Afterfollow exits and returns; measure water, land and income; remedy loss; monitor destination areas

Exception: an imminent threat to life or an irreplaceable ecosystem can require emergency restriction. Emergency action still creates duties to protect affected people and provide remedy.

cross-study synthesis

Do not mistake movement for reduction

Four forms of displacement require different evidence

Mining relocation

Workers, equipment and extraction move.

Trade diversion

Gold takes another route while extraction stays.

Origin laundering

Documents or intermediaries conceal mine origin.

Environmental spillover

Water, sediment or exposure crosses boundaries.

ECOWAS cooperation should connect customs and finance with labour rights, migrant protection, watershed monitoring and livelihood support.

regional mechanism evidence

No retained study evaluates an ECOWAS just-transition package. Export growth in a neighbouring country does not by itself prove mine relocation.

Actors in Ghana

Put rights-holders at the centre; map power around them

Rights-holders

Workers by role, women inside and outside mining, tenants and owners, migrants, former miners, children, caregivers, downstream and forest-edge communities, other resource users and future land users.

Duty-bearers

Districts, Minerals Commission, EPA, Water, Forestry, Lands, COCOBOD/agriculture, labour, health, social protection, police, courts and Parliament.

Commercial & political power

Land and mineral-right holders, operators, equipment, financiers, traders, GoldBod buyers, refiners, large mines and political networks.

Independent accountability

CHRAJ, Auditor-General, courts, Ghanaian universities and labs, media, WACAM, A Rocha Ghana, unions and directly accountable community organisations.

governance requirement

Representation

No actor can stand in for everyone affected

Direct representation required

Unlicensed and licensed workers by role; women inside and outside mining; tenants and landowners; migrants; former miners; downstream and forest-edge residents; fishers and other resource users.

Important—but not substitutes

Chiefs, licence holders, cooperative leaders, household heads, professional women's groups, district officials, buyers and NGOs.

A chief is not every customary user. A licence holder is not a worker. A miner is not a downstream resident.

procedural justice rule

No one organisation can deliver the system

Fern can help create an accountable network with four centres of responsibility

Community authority

Define acceptable outcomes, select representatives, monitor harm and use independent grievance/remedy.

Public coordination

Align land, mining, water, farming, labour, health, purchasing and social protection with budgets and outcome targets.

Market obligation

Buyers, refiners, financiers and equipment owners fund verified improvement and remediation instead of dumping cost downstream.

Independent evidence

Ghana-led research, laboratories, audits and public reporting measure harms, distribution, durability and displacement.

network proposition

Recommendation to Fern

Advocate conditions for a just transition—rather than one untested solution

1

Centre Ghanaian leadership

Resource affected-community organisations and Ghanaian researchers to define outcomes, governance and evidence.

2

Set red lines

No criminalisation-first package; no-go areas with protection; no success claim based only on legal status, arrests or exports.

3

Demand sequence

Income protection and tested options before restrictions, except emergency danger; support continues until viability is demonstrated.

4

Shift costs upward

EU buyers, refiners and finance support correction, trace to mines, disclose coverage and remediate—without automatic disengagement.

5

Build independent accountability

Community monitoring, watershed science, worker evidence, public contracts/data and grievance routes outside implementers.

6

Track displacement

Fund district, border and trade-route monitoring with ECOWAS partners, including migrant and destination-community safeguards.

bounded advocacy role

Before advocacy or scale-up

Six decision gates for every proposed initiative

Coverage

Who is missing because they lack title, licence, membership, time or safety?

Adequacy

Does support match net income, timing, debt, risk and duration?

Power

Who controls land, eligibility, price, data, equipment and complaints?

Environment

Will absolute harm fall, including rebound and toxin substitution?

Displacement

Where could people, extraction, finance, gold or pollution move?

Correction

What evidence triggers expansion, redesign, compensation or stopping?

practical screen

The immediate research agenda

Evaluate the package as a system—without averaging away justice

Follow people and places

Track owners, workers, tenants, women, migrants and affected non-miners before, during and after intervention; add destination districts and watersheds.

Measure six domains together

Absolute harm; livelihood security; distribution and recognition; power and procedure; displacement and durability; implementation and cost.

Use designs that fit the claim

Counterfactual evaluation where possible; realist synthesis for mechanisms; separate meta-analysis only for genuinely comparable interventions.

Protect knowledge quality

Ghana-led protocols, open methods, independent laboratories, conflict disclosure, community data governance and publication of null or harmful results.

next-stage methodology

Bottom line

The evidence supports a common architecture—not a universal blueprint

Protect people. Create viable options. Constrain the harmful system. Repair damage. Test the package against distribution and displacement.

Fern need not deliver every component. Its strategic contribution is to help build the relationships, rules, finance and accountability that prevent any one component from becoming another source of harm.
